Reliable flow measurement despite difficult conditions
Schluchseewerk AG relies on noninvasive clamp-on flowmeter Prosonic Flow W 400 for optimized turbine operation
Schluchseewerk AG wanted to record and optimize the efficiency of its turbines at the pumped storage plant in Wehr, Germany, despite difficult flow conditions. For this purpose, it was looking for a reliable flowmeter. Endress+Hauser offers the optimum solution for the challenging measuring point with the clamp-on flowmeter Proline Prosonic Flow W 400.
Tough conditions: Installation at the difficult-to-access measuring point
The clamp-on sensor is simply attached to the pipe
The result
-
Precise measurement despite short inlet runs and disturbed flow profiles thanks to FlowDC
-
Precise determination of turbine efficiency
-
Optimum process control and monitoring
-
Basis for verifying the increase in performance
“Thanks to Endress+Hauser, we were finally able to find a solution for our difficult measuring task. The comparison measurement confirmed the accuracy and reliability of the ultrasonic flowmeter.“
Schluchseewerk AG, Laufenburg (Germany)
The customer requirement
At the pumped storage plant in Wehr, large quantities of water are pumped from a lower basin to an elevated one. When the water flows back, electricity is generated using a turbine and generator. Precise measurement of the water volume is important for recording and optimizing the efficiency of the turbines as the geometry of the impellers was to be changed based on a performance optimization of the turbines. The improved performance should then be verified by a precise measurement.
Our solution
With Proline Prosonic Flow W 400 and the unique FlowDC function, Endress+Hauser offers the optimum solution for the challenges. The noninvasive ultrasonic flowmeter is installed from the outside on pipes. It measures independently of the pressure and is easy to install, saves space and does not interrupt the process. Even with shortest inlet runs (≥2 × DN) and disturbed flow profiles, FlowDC offers consistently high accuracy.
